By date, there are actually no socialistic governments in West Europe.
Denmark is definitly not a socialist country. Norway isn't, either, even though we pay 24% sales/import tax, and we have a much higher tax level on absolutely everything. USA is a republic, and there are clear differences between the US government and any European government. The US economy system is based on losers and winners. "If you aren't a successful person, it's your own fault". There are rich people, middle-class people, lower-class people and poor people. There are more rich people in the US than in Europe, and as a result of that there are of course more poor people, too. That's a matter of fact. In our modern capitalism based regime, money is practically everything. In USA it's even worse. If you don't have money, your children are sent to the chapest, worse school and get much poorer education than they would get if you were rich. If you get cancer, and you don't have money, you're dead.
Capitalism is a sign of limited human intelligence factor. Capitalism has come to stay.
